37. The concept of a trinity of gods also goes against enlightened reason, as many arguments are capable of establishing. What person of sound reason would be open to hearing that three gods created the world? Or that creating and preserving, redeeming and saving, and reforming and regenerating are tasks undertaken by three gods, not one God? On the other hand, what person of sound reason would not be open to hearing that the same God who created us also redeems, regenerates, and saves us? Since the latter thoughts are reasonable, but the former are not, every group of religious and reasonable people on the face of this earth acknowledges that there is one God.

As we all know, Muslims and some of the peoples in Asia and Africa detest Christianity because they believe it entails the worship of three gods. When Christians are rebuked on this account, they have only one response: that the three persons share one essence, and therefore constitute one God.

I can attest that the reasoning power granted me allows me to see that no world, no angelic heaven, no church, and nothing within any of them could have come into existence or could continue to exist if there were not one God.

19. 2 In fact, in regard to the four theological points just listed, Roman Catholics before the Reformation had exactly the same teachings as Protestants did after it. That is, Catholics had the same teachings regarding the trinity of persons in the Divine, the same teachings regarding original sin, the same teachings regarding the assigning of Christ’s merit, and the same teachings regarding our being justified by believing that we are assigned Christ’s merit; the only difference was that Catholics united that faith to goodwill or good works.
